E-mu Proteus 1-XR
Little is documented about the E-mu Proteus 1-XR. The Proteus line was E-mu's sample-based synthesizer/sound module series built on the company's proprietary synthesis engine. The 1-XR variant appears to have left few traces in the period press. Here is what the record shows.
It was a rackmount sound module. The "XR" suffix typically indicated a rackmount or expanded version of earlier Proteus units. Sound on Sound (September 1997, p.268) listed a used unit with the description "Proteus sounds, 16-part multitimbral, six outputs, good condition, boxed, manual, £190 no offers." That same classified entry mentioned a Proteus 1 keyboard version at £300, which places the 1-XR as the rackmount sibling. A studio profile in EQ Magazine (August 1997, p.28) also listed an "E-mu Proteus/1 XR" among the gear at a professional facility, so it saw some studio use.
Beyond these classified sightings and the studio mention, no specifications, release date or original price have been preserved in the available documentation. The 1-XR appears to have been a straightforward rackmount version of the Proteus 1, with the same 16-part multitimbrality and multiple outputs. There is no manual or sales literature in the archive, so most details stay unconfirmed.
